My invention relateS l0, 116W md BSQL improvements in' goggles and hasparticular reference to improved means for securing lenses in theeyecups df goggles.

It iS moet important. obioot of my Hilf vention to, provide intheeyecups of goggles,

lens olsropllf-l:r ineens vhioh, While firmly and securely` clamping,thel lenses, will nevertheless permit of the easy andrapid insertion orremoval of the saine.

In the commercial use of goggles in faef tories and similar' industrialplants, there has constantly been al demand lor means for great manyattempts made to produce an v eyecup for goggles which shall 4have meansfor detaehab-ly clamping: lenses.4 In, so far as I am aware, however,all of these struetures have included comparatively conlplif catedstructures, not only requiring eonsiderable skill to insert or removethe lenses but also greatly increasing the original oost `of the`gOgglgeS- It is` therefore, another important objectI of my inyentiontoprovde'lens Clamping moans for the 'overture otsoselos which shall becheap, to, manufacture, easy.

to use, and olif the utmost Simplicity in every detail'.

My invention further contemplates the provision of lens clamping means'for the eyeoups of goggles whieh shall be Substan tially hidden yfromview when the goggles are being worn, suoli thattliey willdetract in noway from the` good appearanee ofthe goggle.

Referring now'particul'arly to the drawing wherein l have shown thepreferred forms which my invention may take,y the numeral Ll@ designatesa joined as is customary with a nosepiece 11,

Figure. 9 S El tlitHSVeS Sectional view ot pair of eyeeups Y m Figure 5is a topY Plan View oi Pair of and being further provided with thetemple y pieces 12.` These eyecups 10 are substantially cylindrieal inshape7 having one edge curved as "at .13 to conform to. the contour oitthe face, and the opposite edge flat as at 14, for the reception of alens.

In forming an eyecup in accordance withV the preferred embodiment of myinvention, l. internally bore the same as from the edge 1li, toI form anannular lens receiving ShQLlder 15, on the inner periphery of theeyecup, the same being spaced from the edge'll by an annular reducedportion 16. Ateertain predetermined points on the inner periphery of theannular reduced portion 16 'and preferably at diametrically oppositepoints, I form transversely extending grooves 17, cutting the samesubstantially deep to a point 18, from which point I slowly taper thedepth oit the grooves to a point 19 located on the inner periphery ofthe eyecup and substantially beyond the annular shoulder 15.

Mounted in the wall of the eyecup 10 by a rivet 20, or any othersuitable means and fitting snugly into the reduced portion of thetransversely extending groove 17, is a resilient clip 21. As clearlyshown in Fig. 2 of the drawing, this clip extends upwardly towards theedge 14 oit the eye cup 10, and is bent as at 22 to form a U-shaped lensreceiving catch, the outer arm ot' which is enlarged to form a springlip 23.

While the normal position ot the spring clip 21 is as shown in Fig. 2 ofthe drawing, it may be clearly seen that, due to the depth of the groove17, the clip 21 may be depressed suiiiciently to permit of the insertionof a lens, such as 24, past the enlarged lip 23 and into the U-shapedportion of the clip 22. A lens once positioned in this U-shaped portionof the clip 21 will rest upon the shoulder 15 formed on the innerperiphery of the eyecup 10 and will be held 'from displacement by theinherent resiliency of the spring clip 21. In order to remove the lens24 from the eyecup, 10, it is only necessary to either depress thisspring clip 21 by pressing on the outer lip portion 23, thus disengagingthe edge of the lens 24 from the U- shaped portion of the clip 21 orelse to-eXert suihcient pressure on the inner tace of the lens 24 at apoint opposite one ofthe clips 21, to force the same upwardly andoutwardly past the catch 22 which may be forced back into the groove 17providing sufficient pressure is applied.

In Figs.' 5 and 6 of thedrawing, I have shown a modilied form of myinvention, in which the annular reduced portion 16 is cut thru'at twopoints to form the cut out portions 25. .In this form of my invention, aspring clip 26 is riveted as at 27, to the outer periphery of thee'yecup 10 being preferably partially buried therein so as to be evenwith the face thereof. This clip 26 extends upwardly on the outside otthe eyecup 10 substantially to the edge 14 where it is bent inwardly anddownwardly to form a hook section 28. In use, this hook section 28 isadapted to bear upon the edge of a lens 24, positioned on the annularshoulder 15 and to clamp a lens in this position due to its inherentresiliency.

While inserting or removing a lens from this form of eyecup, it isobvious that the clip 26 will be forced outwardly thru the opening inthe annular reduced portion 16 and beyond the plane ot the outerperiphery of the eyecup. In this form ot my invention, the clip 26 iscapable of greater lateral movement than is the Vclip in the preferredembodiment of my invention, but lacks the advantage of being as wellprotected.

In Figs. 7 and 8 of the drawing, there is shown still another torniwhich my invention may take. In practice I construct my eyecup from aresilient liber composition material, which is inherently resilient andfrom which projecting parts may be formed Vwhich shall act as springclips. In this form of my invention, the eye cups 10 are likewiseinternally bored from the edge 14, to form an annular lens receivingshoulder 15 and an annular reduced portion 16.

In Fig. 8 of the drawing I have shown seated on the annular lensreceiving shoulder 15, a lens suchy as 30 which may either be a lensground to some particular power or one' having certain propertiesparticularly applicable for the specific use to which it is to be put,the same being protected by a protection lens 31, spaced from the lens30 byl means of an annular fibre washer 29. In order to prevent theoutward movement ot' these lenses, I have provided an annular resilientclamping ring 32, adapted to bear against the annular reduced portion 16of the eye cup 10 sutliciently to be clamped therein and hold thelensesagainst the shoulder 15. To make more positive the clamping action otthis annular clamping ring 32, I have provided in the annular reducedportion 16, a plurality ot' displaced portions 33, which due to theinherent resiliency of the material from which the eye cup is made, formresilient projections bearing lirmly against the annular ring 32 butcapable of being depressed to permit of the 'removal of the ring andsubsequently the removal of the lenses.

In Fig. 9 of the drawing, I have shown a single lens such as 24, seatedon the annular lens receiving shoulder 15, and held from outwardmovement by a plurality of displaced portions 33. In this form of myinvention, wherein a single lens is used, the annular resilient ring 32may be discarded in that the displaced portions 33 form resilientprojections past which the lens 24 may easily be forced into position onthe annular shoulder 15 although preventing the accidental outwardmovement or displacement of the same.

In Fig. 10 of the drawing, I have shown still another modified form ofmy invention in which the annular shoulder 15 is eliminated and in whicha plurality ot displaced portions 34 are substituted. In this form oitmy invention I provide the displaced portions 34 at certainpredetermined points on the inner periphery of my eye cup permittingthesame to form a stop to prevent the movement of the lens 24 towards therear or the curved edge 13. As in the other CTL atenas@ form of myinvention, I provide displaced portions 33 adjacent the edge 1li of myeye tup for detachably clamping the lens and preventing the same fromany outward movement.

From the foregoing description it will be seen that I have provided lensretaining means for the eye `cups of goggles which will permit of theready insertion or removal of the lenses, and in addition that I haveprovided lens retaining means for eye cups which will securely andfirmly hold lenses from displacement under all ordinary conditions. n

It will further be seen that eye cups constructed in accordance with myinvention shall not only be exceedingly `simple and unencumbered withuseless lens clamping structures, but also will be cheap to vmanufactureand easy to use.

In addition to an eye cup that will-answer the requirements of allcommercial demands for goggles, I have produced an eye cup which will beequally applicable and useful to the average person who desires a pairof goggles for automobile driving or similar unindustrial uses. Vhile Ihave shown and described certain preferred forms which my invention maytake, it is to be understood that I reserve the right to make certain.minor departures and variations therefrom in so far as I remain withinthe spirit of my invention and scope of the appended claims.

Having thus described my invention what` I claim is: j
